In-sung Cho has held down a regular role in the Korea Baseball Organization for a decade and has played for the Korean national team.
While in college, Cho was on the national team. In the 1995 Intercontinental Cup, he was 0 for 8 with a walk and a sacrifice fly, splitting catching duties with Kab-yong Jin. In the 1996 Olympics, In-sung hit .263/.318/.579 with two home runs to tie for the team lead. He threw out 5 of 8 attempted base-stealers.
Cho began his professional career with the 1998 LG Twins and batted .269/~.285/.373 in 84 games, only drawing 3 walks in at least 137 plate appearances. In 1999, the LG backstop hit .254/~.289/.401 in 56 contests. He followed with a .225/~.287/.322 line in 2000.
Cho produced at a .253/~.312/.387 rate for the 2001 Twins. In 2002, he hit .268/~.304/.412 with 21 doubles and 9 home runs; he struck out in 82 of 362 AB. The next season, the Yonsei University alumnus batted .257/~.295/.446 and smacked a career-high 19 home runs and drove home 58. He represented South Korea in the 2003 Asian Championship, splitting catching duties with Kab-yong Jin. In 2004, the LG catcher hit .254/~.322/.358 as his plate discipline continued to improve; he drew 39 walks, 16 more than in any prior campaign.
Cho hit .224/~.288/.368 only in 2005 but still was added to the Korean roster for the 2006 World Baseball Classic and saw more time than Sung-heon Hong, a more accomplished hitter. Cho split time once more with Jin in an international event and went 2 for 9 for the South Korean squad. Cho also played for South Korea in the 2006 Asian Games.
Cho improved to a .245/~.305/.393 batting line in 2006. In 2007, he hit .282/~.336/.432 for his best OPS yet. He had 24 doubles, 13 home runs and a new career high of 73 RBI. He played for Korea in the 2007 Asian Championship and did very well as their starting catcher, going 4 for 10 with a double, two runs and a RBI while throwing out both people who tried to steal against him.
